考考你的逻辑能力

西门吹哨

A payroll report is produced for each pay period that shows:
•        The amount paid by each department for each of three classes of employees
•        The amount paid by each division for each of its departments
•        The total payroll for each division of the company

Which of the following alphabetical input sequences will minimise the data stored by the program?
1)        Class within Department within Division
2)        Division within Department within Class
3)        Employee within Department within Division
4)        Employee within Class within Division
